ICP Electronics Australia is proud to introduce ICP DAS PIR-231-E. In the evolving world of smart technologies, the ICP DAS PIR-231-E emerges as a multifunctional marvel. This innovative device is not just a standard PIR motion sensor, but it also encompasses integrated temperature and humidity sensors, offering a comprehensive solution for a multitude of applications.

One of the primary features of the PIR-231-E is its adeptness in detecting infrared waves, specifically those generated by the human body. Covering a significant diameter of around 8 meters and providing 360° coverage, it ensures optimal indoor motion detection. Additionally, the device boasts an intelligent switching mechanism, automatically activating lights upon motion detection.

Beyond motion, the embedded temperature and humidity sensors empower users with precise environmental monitoring capabilities. This dual functionality positions the device as an indispensable tool for indoor climate assessment and even as a potential fire alarm system.

Connectivity is another strength of the PIR-231-E. With support for diverse interfaces such as RS-485, Ethernet, and Wi-Fi, and compatibility with the DCON and Modbus RTU/TCP protocols, integration with existing infrastructures is seamless. A user-friendly utility augments this by offering intuitive data visualization.

Designed for easy installation and maintenance, the PIR-231-E’s fireproof and aesthetically pleasing casing makes it suitable for diverse settings – from public restrooms and stairwells to parking areas and retail stores. In essence, the ICP DAS PIR-231-E symbolizes the future of smart sensing and environmental monitoring.
